IMPROVEMENT IN MEASURING-FAUCETS.

Specification forming part of Letters Patent No. 18.318, dated June 20,1865.

To all whom it may concern:

Be it known that I, JosEPn NOTTINGHAM SMITH, of Jersey City, in thecounty of Hudson and State of New Jersey, have invented a new andImproved Measuring and Registering Faucet; and Ido hereby declare thatthe followingis a full and eXact description thereof, reference beingbad to the accompanying drawings, making part of this specification-Figure 1 being a top view of the faucet; Fig. 2, a front elevationthereof; Fig. 3, afront view, the handle and plate which covers the dialbeing removed; Fig. 4, a central longitudinal vertical section thereof;Fig. 5, an inner view of the removable head of the faucet, showing theoutlet-valve; Fig. 6, a rear view of the plunger; Fig. 7, a side view ofone of the operating-racks of the plunger.

Likeletters designate corresponding parts in all of the figures.

The faucet has a body, A, (generally cylind rical,) ofsufficientcapacity to contain as much oil, sirup, or other liquid asitmay be required to measure out at one drawing or operation; a thininclosed extension part, B, in which the operating-gear is placed; aninlet-pipe, O, (at the back side,) which is to be screwed or otherwisesecured in the head of a cask or side of a vessel containing the liquid,and an outlet-pipe,

D, at one end projecting downward. These parts ordinarily may be made ofcast-iron. On the front side of the extension B is a circular flange,I), through the center of which and through the whole extension a shaft,g, of an operating-handle, G, or its equivalent, passes. This shaft issuitably secured and packed at both ends, so as to make the extension Bliquidtight. Two vanes or projections, 00 00, Fig. 4, on thehandle-shaft 9 enter corresponding notches in a hub, V, of adriving-wheel, L, inside ofthe extension B, substantially as shown. Thiscog-wheel gears into one of two pinions, M M, which contain an equalnumber of teeth, and gear into each other, as also gearing respectivelyinto sliding racks N N, attached to the plunger, all substantially asrepresented in Fig. 4. The two pinions are held in proper positioninrelation to the drivingwheel to each other and to both of the racks bymeans of two face-plates, one of which is shown at m in dotted outlines,Fig. 4, the other one being on the other side of the gear wheels. Onturning the handle G, and revolving the cog-wheel L and pinions M Mthereby in the direction shown by the arrows thereon, it will be seenthat the racks N N, and consequently the plunger, will be moved forwardin the body A of the faucet.

The plungeris composed of two rings or short cylinders, O P, anda head,R, which constitutes a valve for transmitting the liquid through theplunger. The rear ring, 0, has the racksNNsecured to it, and the forwardring, P, has the valve It mounted onit. Aflange of the ring Pfits andslides inside of the ring 0, and a central or diametrical cross-bar, 1),thereof serves to admit two screws, 12 n, which also screw into twoinward projections, 0 0, of the ring 0 and fasten the two ringstogether; and not only this, but they tighten the packing s, which issituated between the two rings, as represented in Fig. 4. The valve R isa disk covering the whole interior space of the ring P and shuttingagainst the front edge thereof, but, being of less diameter than theinterior of the bodyA of the fancet, it allows the liquid to pass aroundits edge. It has a suitable packing-disk, r, and a guideplate, 10, whichboth holds the packing inplace and shape and, by means of guideprojections t t t t, Fig. 6, fitting inside of the ring P, keeps thewhole valve in a central position. The valve is held to the ring P by acentral screw, q, passing through the cross-bar p of the ring, and isclosed, when the plunger is not moving backward, by a spring, Q, bearingagainst the rear side of the said ring, substantially as represented;but when the plunger is drawn back by reversing the handle G thepressure of the liquid from the cask or vessel and of the atmosphereovercomes the force of the spring Q and opens the valve, so that theliquid passes through the plunger and fills the body A of the faucet infront of the plunger, ready to be discharged at the next forwardmovement of the plunger. The pressure of the liquid behind theplunger-valve also has a tendency to separate the ring P from the ring0, (if play is allowed,) and thereby to loosen the packing, renderingthe movement of the plunger more free; but in the forward movement ofthe plunger the pressure is the other way and tends to tighten thepacking when it is required to have it tight. As the plunger movesforward its pressure on the liquid in front causes the outlet-valve U,Figs. 4 and 5, to open and allow the liquid to run out through theoutlet-pipe D. This valve U is a common clack-valve, the hinge andpacking-face of which may be secured between two metallic disks of theheadT of the faucet. The valve is kept closed tight, except whendischarging the liquid, bya spring, 2, located in a chamber, d, overtheoutlet-pipe, D, and into which the valve swings when opened. The plungermoves forward till it touches the head of the faucet and expels all theliquid in front of it. The amount of liquid drawn out at each stroke ofthe plunger is determined by the distance it moves back in the body A ofthe faucet, and this distance is determined and gaged by means ofprojections Y Y on the dial-disk cover E, against one of which a stop,K, on the handle G strikes, and prevents the handles being moved fartherin that direction. These projections are at different distances from thecenter of the handles motion, and the stop K is adjustable to differentdistances from the same center in a slot, k, and held by a thumb-screw,so that the stop may strike either of the projections required. Thus,say, if the upper projection gages to a quart, the lower one may gage toa pint, and either a quart or a pint may then be drawn out at onemovement of the handle backward and forward, according as the stopstrikes one projection or the other. Not only is the amount drawnmeasured by this gage, but a dial, H,

, is arranged so as to register the aggregate bored to indicate theunits of measure, (as gallons,) so as to be able to register the wholeamount which the cask or vessel will hold at one time. The units aresubdivided as required, and there is a set of ratchet-notches in theinner edge ofthe ring, one for each subdivision of the units. The ringis actuated the distance of one notch or more at each forward movementof the handle G by means ofa suitable. pawl, J, Fig. 3, which is movedbya cogged segment, I, gearing into a pinion, 0, on the handle-shaft g,and turning on a central pivot, i. The center pin of the pawl J fitsinto a hole,j, in the segment I. There may be two or more holes, jj, atdifferent distances from the center 13 of the segments motion, so as tocorrespond inversely with the different gage-stops for the handle G, inorder not to disturb the register by the change in the amount drawn at atime, or in order that the unit may be changed, if desired. The dial isread through an aperture, 6, in the case E, where it comes in range withan index-rod, h, Fig. 2, or its equivalent. As the liquid flows throughthe inlet-pipe 0 it enters the extension B of the faucet-body, fillingaround the operating-gear therein.

The body A is lined with a sheathing, a, Fig. 4, of tin, brass, or othersoft metal or alloy, which is retained concentrically therein by abacking, W, of hydraulic lime, plaster-of-paris, or other suitablecement or substance, so that the plunger mayrun with little friction,and the lining may be removed and replaced at pleasure.

What Iclaim as my invention, and desire to secure by Letters Patent, is-

1. Introducing the liquid to be measured into the faucet behind a valvedplunger, through which it is transmitted in the backward stroke thereof,and by which it is forced out from the faucet in the forward stroke,substantially as and for the purposes herein set forth.

2. The outlet-valve U, keptclosed by aspring, in combination with thevalved plunger of a measuring-faucet, substantially as and for thepurpose herein specified.

3. Actuating the plunger by a handle, G, or its equivalent through themeans of a gearwheel, L, and two equal-sized pinions, M M, gearingrespectively into the plunger-racks N N arranged and operatingsubstantially as and for the purpose herein specified.

4. The adjustable stop K on the handle G, and stationary pins orprojectionsYY, in combination with a measuring-faucet for gaging theamount of liquid drawn byeach movement of the handle.

5. The registering-dial H and index h, arranged in combination with theactuating-handle, so as to indicate and register the whole amount ofliquid drawn from the cask or vessel, substantially as herein specified.

6. The combination and arrangement of the plunger in relation to theoperation of its valve and packing, substantially as and for thepurposes herein specified.

7. In combination with a measuring and reg istering faucet, lining thebody of the faucet with tin, brass, or other suitable soft metal oralloy, backed by a cement of hydraulic lime, plaster-of-paris, orequivalent substance, so that the lining may be removed and replacedwhen desired, substantially as herein specified.

The above specification of my improved measuring-faucet for oils,molasses, and other liquids signed by me this 21st day of December,1863.
